I have the local stereo shop stopping my to give an estimate on an in wall speaker system. When I stopped by their store they had a set of klipsch reference set up. The price was around $350 area retail for a 6.5" woofer. The $350 area is out of my price range as I will be building a system from scratch. I was looking at R-2650 $200 each and the R-1650 $150 each. How are these speakers? There is a possibility I may go with a in ceiling speaker for surrounds. I will get the installers opinion first. I have been a fan of Polk in the past but I am sure the Klipsch is just as good. My room is 14' x 16' with vaulted ceilings. Would something with a 6.5" woofer be fine? I will get either a Denon 1912 or a Yamaha RX-V671 receiver so there will be plenty of power. As for a sub they suggested a 10" Klipsch (SW 450 or SW110). Would a 10" be big enough? Basically I am new to the in wall type stuff. What questions should I be asking the installer when they come by my house for a quote and suggestions?
